Having discerned a suitable satellite constellation for coverage over specific user-defined regions of interest in part two, part three will see us compute a conjunction analysis for the proposed LEO constellation.
In part one of this satellite design series, we explored the modelling of a physics accurate RF Comms link between ground facility and LEO satellite. However, rarely do modern LEO satellites work in isolation. Instead, they work as part of a larger constellation, continuously exchanging data to fulfil their intended mission. Part two of this series explores the design of a larger LEO constellation and how Ansys STK allows for the qualitative and quantitative analysis of user-specified regions of interest to discern how effective a given constellation will be.
This is the first instalment in our 3-part DME Series that will explore the design of a LEO satellite constellation, exploring the implementation of Ansys STK to tackle common design challenges, including the design of a reliable RF communication link, the evaluation of LEO constellations for specific coverage metrics, and the conjunction analysis of the proposed constellation to ensure satellite survivability.
In the world of satellites, there’s a new game-changer: Low Earth Orbit (LEO) constellations joining hands with Global Navigation Satellite Systems (GNSS). What does this mean for us? In this guest blog, Dr. Amir Allahvirdizadeh, Research Fellow at Curtin University explains how LEO-PNT systems help solve numerous challenges when operating in critical environments, ensuring greater reliability and precision than ever before.
